b) Persons and product
• The measuring device is only intended for use with batteries. Never operate it with
a power adapter or other continuous power supply.
• Check the measuring device for damage at regular intervals.
• The measuring device can heat up during operation, ensure optimal discharge of
the generated heat. Do not cover it.
• Only use batteries with a maximum voltage in accordance with the technical data.
Never exceed the maximum specified current.
• Only use high-quality connecting cables and, if necessary, connectors.
• Do not open the measuring device to carry out repairs.
• Disconnect the battery after using the measuring device.

Setup
a) Connection
• Connect the battery (power supply) to the
IN
connection (3) on the measuring device. Ensure
the correct polarity when connecting. The red connection must be connected to the positive
terminal and the black connection to the negative terminal. The polarity is indicated on the
housing.
• Connect the consumer to be measured to the
OUT
connection (2) on the measuring device.
Ensure the correct polarity when connecting. The red connection must be connected to the
positive terminal and the black connection to the negative terminal. The polarity is indicated
on the housing.
Always use high-quality connecting cables. Otherwise, the measured values may
be distorted. Ensure that short circuits cannot occur. You are responsible for proper
connection of the device.
• Disconnect the battery from the Watt meter after use.
• You can affix the Watt meter to a suitable surface after establishing the electrical connection
with the help of the double-sided adhesive strips supplied.
• Remove the protective film from one side of the adhesive strip and affix it to the back of the
Watt meter.
• Then, remove the second protective film and affix the Watt meter to a suitable surface.
b) Operation
When sufficient voltage is applied, the measuring device will work. All display values are reset.
The LC display firstly displays the voltage value in V.
• Press the
Switch
button (1) once to display the next parameter in the display loop. The
loop is: Voltage (V) > Minimum voltage (Vm) > Current (A) > Current peak (Ap) > Power
consumption (W) > Maximum power consumption (Wp).
• The indicators on the LC display are refreshed every 0.5 seconds.

Voltage with minimum voltage value
• The present voltage value is displayed in V in each case. The minimum value indicates the
lowest, measured voltage "Vm" since the beginning of the current measuring cycle.
Current with peak value indicator
• The present current value is displayed in A in each case. The current value is indicated in the
display loop with "Ap" and represents the short-term peak value.
Current power consumption and maximum value
• The current power is displayed in W. The power value "Wp" is the maximum power consumed
at a point in time.
Care and cleaning
• Always disconnect the product from the power supply before cleaning it.
• Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these may
damage the housing or cause the product to malfunction.
• Use a dry, lint-free cloth to clean the product.
Operating instructions
Mini wattmeter
Item no. 1877013
Intended use
The product is used to determine the following values: the voltage (V) with minimum value (VM)
indication, the current (A) with peak value (Ap) indication, the power consumption (W) with
peak value (Wp) indication. The connections on the measuring device have reverse polarity
protection. The device has low power consumption and no excess voltage/current protection,
but can withstand a surge of up to 40 V without sustaining damage. An LC display indicates the
data in a manually switched display loop.
This product is intended for indoor use only. Do not use it outdoors. Contact with moisture (e.g.
in a bathroom) must be avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or modify this product. Using the
product for purposes other than those described above may damage the product. In addition,
improper use can cause hazards such as a short circuit, fire or electric shock. Read the
operating instructions carefully and store them in a safe place. If you pass the product on to a
third party, please hand over these operating instructions as well.
